To all whom it may concern.-

Be it known that we, MATHIAS F. QUEsT and MAX F. REIoH, citizens of theUnited States, residing at St. Louis, State of Missouri, have inventedcertain new and useful Improvements in Barrel-Forming Machines, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming a part hereof.

Our invention has relation to improvements in barrel-forming machines;and it consists in the novel construction and arrangement of partsmorefully set forth in the specification, and pointed out in the claims. aIn the drawings, Figure 1 is a top plan of the invention, showing itsapplication to a complement of staves in the process of forming abarrel. Fig. 2 is a combined side elevation and section on the brokenline 2 2 of Fig. 1, with the heads, however, advanced sufficiently toform the barrel. Fig. 3 is a transverse vertical section on line 3 3 ofFig. 2. Fig. 4 is an enlarged horizontal section on line 4 4 of Fig. 2.Fig. 5 is a vertical sec tion on line 5 5 of Fig. 4. Fig. 6 is alongitudinal section of one of the barrel-forming heads on the line 6 6of Fig. 7, showing the stave-guiding wedges projected into the head.Fig. 7 is a transverse section on line 7 7 of Fig. 6. Fig. 8 is a faceview of a portion of the adjusting-band for the wedges turnedsufliciently to retract the wedges from the path of the staves. Fig. 9is a section on line 9 9 of Fig. 8, and Fig. 10 is a perspective view ofthe temporary clamp for the staves.

The object of our invention is to construct a machine which will bendthe complement of staves which constitute a barrel, at the same timeleveling and trussing the barrel, the necessity of first bending onestave at a time being entirely dispensed with.

A further ob 'ect is to construct a machine which will be simple,readily manipulated, one containing a minimum number of parts, oneoperating on variable thicknesses and dimensions of stock, and onepossessing further and other advantages better apparent from a detaileddescription of the invention, which is as follows:

Referring to the drawings, 1 represents a suitable oblong frame alongthe bottom and adjacent to one side of which is disposed. a longitudinaldrive-shaft 2, having terminal pinions 3. Each pinion meshes with'agearwheel 4, forming an integral part of a nut 5, mounted on the frameand freely rotatable about a screw-threaded stem 6, whose inner end iskeyed or otherwise secured to a conical head 7, the screw-threads of thestems 6 6 being, respectively, right and left hand, whereby the stemsand heads carried by them may reciprocate simultaneously in oppositedirections, as more fully hereinafter apparent, the heads being providedwith guide ribs 7 traveling in suitable grooves or ways formed in theframe. The shaft 2 has keyed thereto at one end a clutch member 8,having conical engaging surfaces on each side of the center thereof,these surfaces being made to alternately and frictionally engage theconical surfaces of the depressions 9, formed in the pulleys 10 10,freely sliding over the shaft, the said pulleys constituting the femalemembers of a clutch, of which the part 8 is the male member. From thepulleys 10 10 lead the open and cross belts 11 12, respectively, wherebyupon the engagement of one pulley or the other with the member 8rotation is imparted to the shaft 2, first in one direction and then theother, an intermediate or central position corresponding to a disengagedposition for both pulleys, the belts leading to any suitable source ofpower or line-shaft. (Not shown.)

The mechanism for shifting the pulleys may be of any prevailingconstruction, that here shown being as follows: Each pulley has an outerhub portion 1 3, which is encompassed by the intermediate looped portion14 of a 'horizontally-oscillating arm 14 pivotally secured at one end toa bracket 15 of the frame, the outer slotted ends of the arms beingcoupled to a link 16, whose terminal slotted ends play over the pins 17at the ends of the brackets or arms 18, projecting from the frame. Byseizing the terminal knob or pin 19 of the link and shifting the latterfirst in one direction and then the other one or the other of therotatable pulleys may be brought into frictional engagement with themember 8 of the drive-shaft, and since the pulleys are constantlyrevolving in opposite directions by reason of the open and cross belts11 12 thereof leading to a common line-shaft it follows that thedrive-shaft 2 will be first rotated in one direction and then the other,de-

pending on Which pulley is in engagement with the member8..Anintermediate position of the link 16 OfCO111S8:W1ll disengage bothpulleys from the member 8.

Formed in the upper peripheral wall of 5 each head 7 are a series oftransverse semi-annular openings 20, through which may be dropped intothe head the barrel-hoop h, one

edge of each hoop resting against a circular shoulder 21, formed on theinner surface of the head, the opposite edge of the hoop resting againstthe bases, of a series of curved "'fwedge-shaped segments 22, whoseinclined paces, as presently to be seen, collectively orm a guidingsurface or wedge for ends of '5 the staves as the latter are beingforced toj ward the closed bottoms of the conical heads *7. Each segment22 is provided with a stem -'-'3, rejecting loosely through the wall ofthe ea 7, the stem having a terminal head 24 zoflcfonnected to the bodyof the stem by a neck ,225. These necks pass through elongated slots 26of the transverse bands 27, loosely encompassing the heads 7 adjacentthe open- "Wihgs 20. The slots 26 are disposed in the m? cam formations28 of the bands, each cam 28 *ljaving a terminal shoulder 29 to limitthe roation of the band in one direction. A knob 'or handle 30 isprovided for each band. With the exception of the cam portions 28 the ibodiesof the bands 27 hug the peripheral 'ifl s' urface of the head, sothat if the bands be $1? "'i g'iven a turn in proper direction, Fig. 7,to l-withdraw the earns 28 from under the heads $24 of the segment-stems22 the several stems fwill be forced inwardly, and hence the sev- F eralsegments will be projected inwardly to bear against the adjacent edge ofthe hoop h.

*By giving the band 27 a turn in proper direc- ,tion, Figs. 8 9, tobring the earns 28 under the 48 heads 24 the several segments will beretractedor drawn outwardly into the annular recess 81, formed for theirreception on the in- ?"Tfier wall of the head. In their retractedposition the segments will be virtually flush fi-tivith the inner wallof the head. The com plement of staves S is first assembled and Rtemporarily held in a clamp or strap 32, passed centrally about the bodyof the staves and the whole is placed on a curved support 5 or saddle 33at the top of a centrally-disposed s tandard 34, bolted to the floor.

W The operation may best be described by 5 a reference to Figs. 1, 2,and 6. The comple- "Ument of staves held in the form of a cylinder 5flbythe clamp 32 is placed on the support 33 flfbetween the heads 7 7,Fig. 1. The operator '*then drops the proper size hoopsh into the-''several openings 20, the hoops lodging against the circular shoulders21. Then the bands 06927 are given a turn to project the severalsegments 22 into the heads and opposite the ad t *jhoent edges of thehoops previously introjduced. The operator then by proper shifting ofthe pulleys imparts rotation in proper 6% direction to the drive-shaft2, which simulta- ,tation of the gears 4 4 imparts the necessarilyreciprocating movement to the *stems 6 and heads 7, carried by them, sothat the heads will now simultaneously move toward each other. As theheads thus approach they gradually encompass the staves, causing thelatter to gradually conform to the conical contour of theheads until thestaves are fully bent, Fig. 2, the ends of the staves with the bendingoperation being contracted to progressively narrower limits as theyapproach the bases or the narrow portions of the heads. As the headsthus pass over the staves the hoops h are driven over thegradually-converging ends of the staves and forced over the resultingbarrel, the ends of the staves first passing over the inclined faces ofthe body of segments 22, said inclined faces safely guiding the stavesinto the hoops and preventing the jamming of the ends of the stavesagainst the edges of the hoops, a result which would be inevitable withthick hoops. For very thin hoops the wedges 22 need not be brought intorequisition, Fig. 9, and the same maybe retracted into their recesses31, as a thin hoop will pass over the staves without any danger ofamming or cutting the ends of the staves. When the heads are driveninwardly their full limit, they will come in contact with the ends ofthe staves, and thus automatically level the barrel previously bent andtrussed. When the operation is complete, the machinery is reversed andthe heads will travel away from each other, thus releasing the finishedbarrel. The latter is then ready for the crozing operation and for thereceptionof the heads.

Having described our invention, what we claim is 1. In a barrel-formingmachine, ahollow head of a contour conforming substantially to one endof a barrel and having a series of transverse semicircular openingsformed along its peripheral walls for the reception of a correspondingseries of hoops, substantially as set forth.

2. In a barrel-forming machine, a hollow head contoured interiorly toconform to one end of a barrel, and having a series of transversesemicircular openings formed along its peripheral walls for thereception of a corresponding series of hoops, and formations on theinterior of the heads for guiding a complement of barrel-staves alongthewalls of the head and past the hoops, substantially as set forth.

3. In abarrel-forming machine, a hollow head contoured interiorly toconform to one end of a barrel and having a series of transversesemicircular openings formed along the peripheral walls for thereception of a corresponding series of hoops, and a series ofwedge-shaped segments carried by the walls of the head and distributedadjacent to the hoops, and collectively forming an annular guide for thestaves in their passage into and through the hoops, and means forretracting the segments out of the path of the staves, substantially asset forth.

4. In a barrel-forming machine, a hollow head contoured interiorly toconform to one end of a barrel and having a series of transversesemicircular openings formed along its peripheral walls for thereception of a corresponding series of hoops, a series of Wedges apedsegments distributed adjacent to the hoops, stems carried by thesegments and passed loosely through the walls of the head, terminalheads on the stems, and rotatable bands encompassing the head, the bandshaving a series of slotted cam formations, and necks connecting thestems to the terminal heads loosely passed through the slots of saidcams, whereby upon rotation of the bands in proper direction, thesegments may be collectively forced inwardly beyond the walls of thehead or retracted into suitable recesses formed for their reception,substantially as set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
